HelloworldJsp中引入tomcat-juli处理
OS：centos66
eclipse jee-Mar.1
tomcat6
jdk1.8
找了一篇HelloworldJSP的文章来学习Jsp。
大体流程:
1 创建动态网页项目
2 增加jsp文件
系统自动协助创建了jsp内容。
3 编译执行。
编译执行出的错误如下，
Exception in thread "main" java.lang.NoClassDefFoundError: org/apache/juli/logging/LogFactory
at org.apache.catalina.startup.Bootstrap.<clinit>(Bootstrap.java:55)Caused by: java.lang.ClassNotFoundException: org.apache.juli.logging.LogFactory

错误是说org/apache/juli/logging/LogFactory没有找到。这个类在tomcat-juli.jar中，需要引入到ClassPath里面。
引入方法：
(由于本人的eclipse版本window-preferences-tomcat下没有tomcat4.0||tomcat5.0||tomcat6.0等版本信息）
1.在eclipse的project explorer的workspace上，有多个项目，包括HelloworldJsp，还有一个Servers项目。
选择Servers项目
2 右键有Run As, Debug As等菜单项，选择其中的Profiles as->Profile configurations...，会弹出Create, manage and run configuration选项卡
3 选中弹出的选项卡的Tomcat6->Classpath选项卡
4 在此选项卡的User Entries中，选择Add External jars，将/usr/share/tomcat6/bin/tomcat-juli.jar选入。
此后编译成功了。
这是结局。
